Study Notes
Arguments from Reason
- Ontological arguments attempt to prove God's existence based on the definition of God, using reason and logic instead of experience.
- A priori arguments, meaning they don't rely on experience.
Anselm's Ontological Argument
- Anselm (1093-1109), a British Catholic monk, presented an ontological argument in his book "Proslogion".
- His argument emphasizes "faith seeking understanding," aiming to strengthen faith through reason.
- The argument is a priori, relying solely on logic and reasoning, not on experience.
- Anselm defines God as "that than which nothing greater can be conceived." This means God is the greatest possible being.
- God's existence in reality is greater than simply existing in the imagination.
- Therefore, God must exist in reality, because existence in reality makes God greater. If God does not exist in reality, then something greater than him could be conceived. A simpler form of this is:
- God is that than which nothing greater can be conceived.
- Existing in reality is greater than existing in the imagination.
- God must exist in reality, or else something greater than him could be conceived, contradicting his definition.
Anselm's Second Ontological Argument
- His second argument focuses on God's necessary existence.
- Necessary existence is existence that does not depend on anything else.
- Contingent existence is existence that depends on something else.
- God must exist in a necessary way, because a necessary existent is greater than a contingent existent
- Anselm argues that God, as the greatest conceivable being, must have necessary existence, because a necessary being is greater than a contingent being.
Gaunilo's Criticisms
- Gaunilo, a contemporary of Anselm, critiqued Anselm's argument using a reductio ad absurdum.
- Gaunilo used the concept of a "greatest possible island" to argue that Anselm's method could prove the existence of anything imaginable.
- Gaunilo's first criticism is a reductio ad absurdum.
- Gaunilo said that Anselm's argument could be used to prove the existence of the greatest imaginable island.
- If there is a greatest imaginable island (with maximum perfection), then it would have to exist in reality, because being real is better than existing only in thought.
- His argument shows that if Anselm is valid, then every imaginable concept can be shown to exist in reality.
Plantinga's Response
- Plantinga argues that Gaunilo's criticism is invalid because it doesn't apply to God in the same way it does to an imaginary island.
- God has intrinsic perfection, unlike an imaginary island.
Descartes' Argument
- René Descartes, a French philosopher and sceptic, independently presented an ontological argument.
- He focused on the concept of perfection to argue for God's existence using a similar argument structure to Anselm. God is the supremely perfect being, by essence, and by perfection. This, by essence, would necessitate existence as a perfection.
Kant's Criticisms
- Immanuel Kant argued that existence is not a predicate, meaning it cannot be a characteristic or property that can describe something. It is a way of classifying something into a category in our understanding.
- Kant's criticism of ontological arguments is that existence is not a characteristic like other attributes.
- Kant argues that you cannot deduce existence from a description. Thus analytic statements (statements that are only about ideas) cannot give us synthetic statements (statements that are about reality), as the idea of God doesn't imply his actual existence.
- Malcolm countered Kant and argued that necessary existence is indeed a predicate.
